What is BMI?
Body Mass Index (BMI) is a numerical value calculated using your weight and height. It provides a rough estimate of whether your weight is healthy in relation to your height.
While BMI is a useful screening tool, it does have limitations. It doesn't account for factors like muscle mass, bone density, overall body composition, or ethnic differences.

Body Fat Categories
| Classification | Women | Men |
|---|---|---|
| Essential Fat | 10-13% | 2-5% |
| Athletes | 14-20% | 6-13% |

Understanding Body Fat Percentage
Body fat percentage represents the proportion of your total body weight that is composed of fat. The estimation provided is based on the BMI method, which gives a rough approximation.
For a more accurate measurement, consider methods like DEXA scans, bioelectrical impedance analysis (BIA), or skinfold measurements.

Why Body Shape Matters
Your body shape, determined by how fat is distributed throughout your body, can indicate potential health risks.
Apple Shape (Abdominal Obesity): Fat accumulation around the waist and abdomen is associated with higher risk of heart disease, diabetes, and metabolic syndrome.
Pear Shape: Fat concentration in hips and thighs typically poses lower health risks than abdominal fat.
Waist-to-Height Ratio: Should ideally be less than 0.5 for most adults. A measurement of 0.5 or higher indicates increased health risks.

About Ideal Weight Calculations
These formulas provide estimates of ideal weight based on height, gender, and in some cases, body frame size. Each formula uses a different approach, which is why the results may vary.
Remember that these are general guidelines. Factors like muscle mass, body composition, age, and overall health should be considered when determining your most healthy weight.

BMI Limitations
While BMI is a useful screening tool, it has several limitations:
- Doesn't distinguish between muscle, fat, and bone mass
- May overestimate body fat in athletes and muscular individuals
- May underestimate body fat in older persons and those who have lost muscle mass
- Doesn't account for ethnic and racial differences in body composition
- Doesn't measure body fat distribution, which is important for assessing health risks
For a more comprehensive health assessment, this calculator incorporates additional measures like waist circumference, body fat percentage, and waist-to-hip ratio.
